Definitions

  • Electrical devices operate on power supplied by a power source. Ensuring the correct power is supplied to a device is important to avoid damaging the device. A too high current or voltage may damage an electrical device. Some devices operate exclusively on an internal power source such as a battery, solar cell, etc. Other devices operate exclusively on a main power supply. Yet other devices operate on a combination of internal power and the main power supply.
